tapping with a soft mallet. You can also use an
appropriate pry bar to pry the seal off the spindle,
being not to gouge the shoulder.
NOTE: The seal may have come off the spindle when the hub was removed.
WHEEL BEARING INSPECTION
WARNING: Please thoroughly clean bearing surfaces and cones. Do not mix a synthetic base
grease or oil with an organic/mineral base lubricant.
Do not spin fry bearing cones with compressed air. Bearing damage may result.
After removing the axle hub, clean excess grease from the bearing cones. Inspect bearing cones for
damaged rollers. Inspect bearing cups for damage to raceway. If any damage is found, replace the

HUB SEAL INSTALLATION
The following instructions apply to installing hub seals in new TMC axle beam assemblies and servicing
TMC complete axle assemblies.
WARNING: To avoid damaging the wheel seal, support the hub and drum until the outer bearing
cone and adjusting nut are installed.

bearing spindle threads, wheel seal surfaces and cotter pin holes. If installing the seal in an in-service
axle, go to Step 2.
2. Remove all dirt, chips and hanging burrs from wheel or hubcap, making sure they are clean and dry.
WARNING: Never install the seal in the hub and then force it into the axle spindle by tightening
the axle nut.
3. Using seal installation tool, place seal on spindle with printing "FLUID SIDE" facing the end of the
spindle. Tap lightly to seat seal.
4. Rotate the seal installation tool in V4-turn intervals until the seal is properly seated with the metal
face of the seal flush with the inner shoulder of the axle spindle.
5. Check for burrs or chips after installation.

WHEEL BEARING ADJUSTMENT PROCEDURE
Castellated Single Nut - Parallel Spindle TP Wheel Bearings.
It is recommended that the wheel bearing in new axles (or whenever the wheel bearings are replaced in
service) are adjusted after the first 5,000 km. The wheel bearings should then be adjusted at 100,000 km
intervals for the axle’s service life. These are the minimum recommended service requirements,
dependent on service conditions more frequent service and maintenance schedules may be required for
correct operation of the trailer axle.
Recommended wheel bearing adjustment procedure:
1.
2.
3.
4.
5.
6.
7.
Install bearings and wheel or hub on axle.
Install bearing tab washer.
Install wheel bearing adjusting nut. Screw nut against the bearing tab washer.
Ensure that the hub rotates freely in both directions. If any brake drag (binding) is felt temporally
back off the brake adjustment to ensure free rotation of the hub.
Rotate the hub in both directions and at the same time tighten the wheel bearing adjusting nut
until a torque setting of 150/180 Nm is reached.
Then back off the adjustment nut so that the cotter pin can be installed in the first hole.
Install cotter pin and lock in place.

BRAKE ADJUSTMENT – MANUAL SLACK ADJUSTERS
‘S’ Cam brakes are adjusted by the manual slack adjusters fitted to the camshafts on the axle.
1.
With the brakes released, adjust the slack adjuster until the brake linings contact the brake drum.
This is done by rotating the 19mm hexagonal nut clockwise.
2.
Adjust the 19mm hexagonal nut back one half turn or until the hub rotates freely with no brake
drag evident.
3.
Finally check that with the brakes released and applied that the angle between the brake chamber
push rod and slack adjuster is greater that 90 degrees. The angle can be adjusted by screwing the
push rod clevis backwards or forwards along the push rod thread to achieve the correct angle.
When finished always check that the push rod clevises lock nut is tightened.

BRAKE ADJUSTMENT - MANUAL SLACK ADJUSTER.
BRAKE ADJUSTMENT – AUTOMATIC SLACK ADJUSTERS
‘S’ cam brakes fitted with automatic slack adjusters should require no manual adjustment after the initial
installation on the axle or initial re adjustment of the brakes after brake relines. All automatic slack
adjusters have a specific set up and installation procedure as specified by the automatic slack adjuster
manufacturer. This procedure must be adhered to. If in doubt contact the manufacturer of the automatic
slack adjusters or the manufacturer’s agent for these specific procedures.
Generally, automatic slack adjusters must be re adjusted similarly to the manual slack adjusters on initial
installation or after brake relines.
Caution: Please refer to the manufacturer’s recommendations.
